------------------------------------

             Summary: Hiveserver2 Memory leak in ObjectInspectorFactory cache
                 Key: HIVE-10739
                 URL: https://issues.apache.org/jira/browse/HIVE-10739
             Project: Hive
          Issue Type: Bug
          Components: HiveServer2
            Reporter: Binglin Chang


User issue multiple "add jar" to add thrift classes to classpath and create table or doing query using those thrift serdes. 
After session is closed, there is still class and objectinspector instance live in the cache, so the classloader for the class and all the other referenced class and static fields cannot be freed.
We may need to provided an option to create inspector without putting it to cache.
